The blue capsule in the PathDemo, rendered to HTML:

```diff
 <svg style="width: 100%;height: 100%; overflow: visible;">
   <rect
     x="0.0"
     height="100%"
     width="100%"
     y="0.0"
     ry="50%"
     stroke-width="0.0"
   ></rect>
-  <path style="stroke-width: 0.0;" d=""></path>
 </svg>
```
